The heats of formation of a series of m-and p-substituted benzene and toluene derivatives, Ar-Y and ArCH,.Y, and their phenyi or benzyl cations, anions, and radicals were calculated by the semiempirical AM1 MO method. Using this data and either the experimental values for the Y species or those obta
